• The Windmill Palm

    The windmill palm (Trachycarpus fortunei) is one of the hardiest palms available to grow indoors or outside in the garden. This cold-hardy palm is also great for northern gardening climates as it can withstand freezing temperatures as low as 10 degrees. 

    It is  a slow-growing plant that will take years to reach its full height of 6 feet indoors. Moreover, this plant is a great choice outside in the garden for water conservation, as it is drought-tolerant and resists pests.

    Basically this plant is easy to grow and care for, as it grows well in full to partial sun and adapts well to most climates and soil types. The highly ornamental palm has stiff, fan-shaped leaves that are beautifully compacted and resplendently green, radiating from its stem on a sturdy trunk.

    Here is what mine looks like:

  • Same outcome, different results

    Follow up to previous post: initial numbers from election night looked like Trump over-performed polling averages between 3 – 5%. My calls for OH, NC and FL went the other way and lo as such, election day became election week. Final tallies TBD due to the closeness of GA and AZ. (and maybe WI — haven’t looked lately)

    I’ve been returning periodically to the passage below from Heather Cox Richardson and mean to sit with it a while in the days to come:

    This election was not particularly close, but pundits warn that the fact that 70 million Americans voted for Trump and 74 million and counting voted for Biden shows that we live in two very different Americas, and that, for all his talk of unity, Biden will have a hard time finding common ground with Trump supporters.

    Pundits suggest that the two different political ideologies in America are about values and principles, but it actually seems that the primary difference between the two camps is between those who are living in a fictional world, created by generations of right-wing media, and those who are living in the real world, the so-called “reality-based community.” According to political historian Rick Perlstein, a scholar of the right, talk radio host Rush Limbaugh has been telling listeners that Democrats have stolen the election, and urging his listeners to abandon the Republican establishment, which did not sufficiently back Trump.

    Entertainment personality Alex Jones is more extreme. He showed up to the Maricopa County, Arizona, counting center, where he told the crowd that “The Bidens are Communist Chinese agents” and urged listeners to fight “those scumbag Nazi bastards.” Jones owns a far-right conspiracy theory website aptly named InfoWars. According to an article by Veit Medick in Der Spiegel, about two-thirds of his income comes from the merchandise he sells to combat the conspiracies he talks about.

    The Republicans’ alternative reality is quite literally deadly. Although 82% of Trump voters believe the pandemic is at least somewhat under control, today America had more than 122,000 new infections, and more than 1100 people died. An analysis by the Associated Press shows that 93% of the 376 counties with the highest numbers of coronavirus cases per capita voted for Trump.

    The emphasis is mine, but in a victory lap where Democrats keep mentioning “Science” in their speeches, and Republican activists are in front of polling sites yelling “fake news” it seems epistemology is an elephant in this room we share.

  • 368-170, Biden wins

    November 1, 2020
    Uncategorized

    My prediction for the final Electoral Results in the 2020 race is an immediate Biden win, called on election night; with an eventual blowout margin at 368 e.c. votes to only 170 e.c. votes for Trump.

    Biden’s lead nationally–somewhere around 10% over Trump–when coupled with what appears likely to be a record-setting electoral turnout, will translate into Biden taking most of the battleground states, including FL, NC and GA where he is currently ahead in most models — and Ohio depending on who you ask.

    If I am correct, it’s basically all settled Tuesday night. Either NC, FL, or GA should be called on election night, possibly all three decided by midnight, ET. This is how the evening starts and will have a lot to say about the prospect of a quick result.

    En route to final calls for these three States, what I’m looking for early on in the Southeast are indicators that Trump is under-performing his final 2016 percentages, by county, in any Southeastern state that should have the quickest results (looking at Delaware, Tennessee, South Carolina and Florida for this) **once 100% precincts have reported** in any given county. (note: I expect an under-performance)

    Of particular interest to me, my home state of Florida, and the largest counties outside of Miami-Dade (which is always the last to report):

    CountyTrump totals 2016:
    Broward County, Florida31.4%
    Palm Beach County, Florida41.2%
    Hillsborough County, Florida44.7%
    Orange County, Florida35.7%
    Pinellas County, Florida48.6%
    Duval County, Florida49.0%
    Lee County, Florida58.7%
    Brevard County, Florida57.8%
    Polk County, Florida55.4%
    Volusia County, Florida54.8%
    Pasco County, Florida58.9%
    Sarasota County, Florida54.3%
    Florida – final vote percentages for Trump in 2016

    New Hanover County, North Carolina was tagged by Dave Wasserman as his bellwether county for the state and if it’s good enough for Wasserman… well. In 2016, 49.5% of the vote went for Trump in that county, and NC ended up at 49.8% for the Orange one. North Carolina is expected to start off with a blue mirage on election night, with a dramatic red-shift. NC could be called that night. (If it is not, the subsequent votes that arrive through Nov. 12 will likely favor Biden). Biden is up +2 in the FiveThirtyEight model and that should be enough to get it done on election night.

    After the Southeastern states are called or around that time, results from Minnesota and Wisconsin should likely be coming in. Biden will win both by morning, but once GA, NC and FL are in the bag, the question is simply how quickly we can get to 270 and have FOX News call the race for Joe Biden. Assuming one is called (MN, lets say) and the other (WI) is still counting, ten electoral votes are in-hand and Mountain states are up.

    In this case, either Arizona, Colorado or New Mexico will race to be the Zombie Bite that ends Trump’s presidency. The first to go blue seals his fate, full stop, and guarantees* Biden reaches 270 no matter what was going on, or will go on, *anywhere* in Maine, *anywhere” in Nebraska, or in Pennsylvania, Iowa, Nevada, Texas, Wisconsin, Michigan, Hawaii (good luck!), Arizona (if Colorado is first) or Ohio. (all of these states I have for Biden, minus Iowa and Texas for what that’s worth)

    Straight-up, DJT could ‘keep the change’ at that point and it’d still be over. CA, OR and WA are 74 untouchable shades of blue and my guess is that the map that will call the Presidency will look something like this (though I’m betting Colorado is the Zombie bite) by midnight, Oakland time.

    Obviously, so long as Biden wins, I’m good; this is more something I wanted to put down ahead of time as I worked through exactly how I expect election night to go and something to explain my thinking to anyone who asks between now and Tuesday evening.

    My final map, to compare against eventual results is as follows:

As much as we want to believe we can operate independently of politics and it’s all about the science, it took just a few months to  hobble our ability to steer the course of this pandemic. So we can pretend that the politics don’t matter, but we have been kneecapped.”

    Jacob Hacker and Paul Pierson are two go-to political scientists anyone should listen to if they find themselves suddenly considering the disconnect between the legislation routinely fought for by the GOP–legislation that ultimately provides most of its benefits toward the über-rich–and the economic station that so much of the GOP base find themselves in. Their latest book together, Let Them Eat Tweets, focuses on this disconnect and the struggle the GOP faces in its commitment to ideals that benefit a plutocratic elite within a democratic framework. They do a fair job of it in my estimation and succeed in making their case that the current GOP serves two constituencies of drastically differing sizes: The über-wealthy on one hand, and a subset of the working and middle classes on the other. Republican elites serve the rich by passing legislation reducing tax rates for corporations and wealthy individuals and by repealing regulations protecting common goods (air, water, etc.); they serve the middle and working classes quite differently though – most often through symbolic and vocal gestures like “defending Christmas” and whatever else seems to have traction in the moment. The authors stay true to their academic pedigrees, making their case with data and analysis rather than ideologically-driven bombastic assertion like so much of the nonsense that shows up on the “Social Science and Current Events” sections of most bookstores of late.

    If they fail–and I think they do on the following point–it is because they have written a book that will only be read by those who have the least to gain from their insights. Their thesis, that the GOP relies on a culture-war obsessed base to fuel the machine’s ability to defund and destroy programs benefiting the majority of Americans in efforts to reduce taxes on the very wealthy, is well-tilled soil. From G.William Domhoff’s Who Rules America? to Thomas Frank’s What’s the Matter with Kansas?, to any of the latest rounds of titles dealing with the impact of Identity and Partisanship on electoral politics (see: Sides, Tessler and Vavreck’s Identity Crisis or Klein’s Why We’re Polarized), I feel like I’ve been reading this book, or some version of it, for the last twenty years. What it offers that the others do not however, is essentially a closer (although not limited) view on the recent events of the last four years or so. But this is not a new phenomenon. The names have changed, but the trends are long-standing.

    The failure in writing to their audience goes beyond the authoring of a book that simply dunks on the folks not reading it (although to be clear, these are solid dunks, impeccably argued and sourced and true). Implicit in their larger argument–explicit in exceedingly limited measure to be fair–is that Democrats should be doing more to focus on the economic and social concerns these currently republican constituencies are focused on. By not calling the party or its members out they do a disservice in my opinion; criticizing the GOP is not enough – more must be sought from the Democratic party and at least a few more pages can reasonably have been expected by the authors on the point.

    When one views parties as simply massive coalitions among differing stakeholders and classes, it is hard to imagine how the Democratic party folds in rural Georgian voters who currently fly TRUMP 2020 flags in their front yard with BLM protestors in Portland demanding police accountability and seeking equal protection under the law. But then, that is the role of a party. To be a big enough tent to get the things done that need doing — not just to narrowly win the occasional election. What Hacker and Pierson have done here is successfully explain how similarly disparate parts of the electorate–a minority with enough money to fund the party, and a majority with the numbers to make winning elections possible–are effectively catered to by the current GOP, with enough success to still be relevant. What I hope to see in the future is a Democratic party that has found better ways to attract a much larger coalition to govern effectively going forward.

    Equally valid, a hope exists that the GOP and its allies either abandons their commitments to the plutocratic elite or shifts their focus to focus on substantive legislative efforts that truly benefit the working and middle classes in this country, ceasing the culture-war lip-service that debases so many of their voters and diminishes the political discourse in the country while doing little to nothing to address the growing inequality in America, or address the challenges that must be confronted for the country to remain a truly indispensable nation in the world. So long as the current model works however, there is little motivation for the GOP to change.

  • brief thoughts from Piketty’s Capital and Ideology

    August 31, 2020
    Uncategorized

    Almost inarguably, Thomas Piketty is among the most considered voices in the global discussion around socioeconomic inequality these days, and the contributions in his latest book, Capital and Ideology, are a clear enough justification for that fact. In his latest book, Picketty, an economic historian, catalogs and assesses the various mechanisms and beliefs justifying social and economic inequality–the inequality regimes—established and used in various societies–across the globe–from (give or take) the 14th Century to the present. He couples this assessment with objective analysis of the present and offers a fair bit of insight into how the understanding of this past may be useful today.

    The scholarship is profound. Coming in at a little over 1,000 pages the book does not limit its focus to the history of inequality of Piketty’s native France, or even to Europe. Significant portions of this book cover the slavery economies of Haiti and other Caribbean Nations, The American South, Brazil, even Britain’s involvement in the trade of enslaved people. The treatment is not brief and in reviewing each instance for the unique characteristics of how inequality was established, discussed, and mainly justified, effort is taken to extract the lessons arising from each. While no work can be exhaustive on such topics, the care is apparent and the insight Piketty provides on these societies was illuminating to me in so many more ways than I can take the time to elaborate. The moral justifications of European Imperialism in Africa are discussed–not just along the Atlantic coast, but in North Africa and extending into the Middle East (Asia) as well–with a particularly insightful explanation of how the preceding military adventures between the countries of Europe simultaneously equipped these ‘colonial’ powers in their pursuits and prepared the economic impetus (if not moral justifications) for all that was to be done. From Africa, Piketty simply rounds the horn and spends time focusing on the role of the British in India and the profound and lasting effects this involvement created via caste and other mechanisms before proceeding to China and the Far East to discuss both the inequality regimes found there and those imposed by the European powers of the era.

    And this is only the first 400 pages.

    As the book progresses, history retains its overall dominance in Piketty’s narrative, while social science increasingly begins to contribute to the work. Grounded in the past, salient aspects from others’ scholarship are added to flesh out a fuller understanding of the dynamics at play in these various societies as the years pass. The book is not precisely chronological, however, it is astonishingly organized, particularly in light of its impressive breadth. “A mile wide but an inch deep” is a phrase often heard in areas where breadth is mentioned as a virtue, but that phrase does not belong here. The book is not a page-turner exactly, but it is not remotely a slog either. It is fascinating. There are over a thousand pages of text in the hardback, so — y’know…it takes time — but it is not dull and it does not belabor. The assertiveness of its statements comes from the work–scholarship that book shows–and not from the exuberant voice of an author clinging to moral sentiment to make his case.

    But morals are not divorced from the text either. Moral impulse pervades the spaces in between as it were, and in a few instances moral questions are contrastingly put forth boldly for the reader’s consideration. There is no shortage of points for consideration, but two main assertions of the book are as follows:

    First: Inequality Regimes are as old as dirt, and just about as varied. Every civilization we have ever created had some form of inequality, and that inequality was justified in some way by a dominant worldview (an ideology) that explained just why it was right and proper that certain folks had so much and others had so little (if anything). The justifications for inequalities, both within and between civilizations, are cloaked in various forms depending on the era and the society: divine providence, the mission-of-civilization, economic necessity, the inhumanity of the subjected, natural order, meritocracy, or some variation of nonsense relating to Horatio Alger and his goddamned bootstraps. In every society, those with more socioeconomic power–not necessarily those with the most, but often a plurality of factions that benefit from the inequality regime–align to maintain a belief that this inequality is justified. The poorest have always deserved it; the reasons just happened to change depending on the time and place. Without an ideological justification to explain inequality, the system would be in danger of collapse.

    Second: There is no reason why any particular justification should be tolerated. Objectively, these inequality regimes are ideologies and Ideologies do not arise from some immutable truth revealed to those who just-so-happen to benefit the most from them. History has many switch points, often found in crises, per Piketty, and the individual trajectories of so many civilizations and the ideologies they employed (and employ today) are the product of the decisions made yesterday and the ones we all make going forward. As fervently as anyone may wish to argue to the contrary, positing that any particular truth objectively justifies societal inequality, independent of history, does not withstand scrutiny.

    Of particular interest to me was Piketty’s discussion of political structures in the modern era – roughly since 1980. “…inequality has increased in nearly every region of the world since 1980, except in those countries that have always been highly inegalitarian,” he writes. He goes into a fair bit of detail in the recent political developments of France, Britain and the US, but he finds a common thread in each, coining (unless I missed the attribution) the terms “the Brahmin Left” and “the Merchant Right” to speak to broader trends transnationally. I confess that by the time I reached these ideas, I fully expected most of the book’s focus to be on The Right(TM) as the instigators and primary defenders of inequality. However, that is ludicrous in hindsight and–as stated “does not withstand scrutiny.” I only mention it here to affirm my own susceptibility to bias.

    Piketty spares no page count though in laying out the failures of the Left and the complicity of those left-of-center–like myself–who having attained a certain degree of comfort owing to the benefits of (economically rewarded) education–reinforce the system, basically in collusion with the others benefiting from the system. Put simply: this is not a book about The 1%; this is not a book about left versus right. This is a book that does not shy away from the role the top several deciles of any socioeconomic order enjoy or at least reify to the detriment and peril of the remaining population, even accounting for the fact that these factions may not work hand-in-glove or even productively on many other matters. The work Piketty does on this point, much of if focussed on “the Brahmin Left” is commendable and personally, I feel a debt of gratitude for his focus on it.

    There is so much research and so much said in this tome, but there is no reason for me to sum up Piketty’s conclusions – he does a fine job himself in the last few pages, a chapter surprisingly titled: Conclusion and there are plenty of reviews available elsewhere. I will say that as someone holding no academic background in history (outside of undergraduate general education requirements) or any background at all in economics–the journey is well worth the ride for all thousand pages. The expanse and scope of the scholarship illuminated much for me and connected numerous dots filling in more than a few gaps in my education — notably on ideas and topics not even mentioned in the book, just through its voluminous context. It is a fine book to pour through, bringing what you already know to the pages within. There is so much information inside, that I suspect it would inevitably provide contexts for a greater epistemic grounding for much that you already arrived with.

    I cannot recommend the book enough.

    The Eisenhower Matrix (image source: https://filterize.net/blog/using-filterize/eisenhower-matrix/

    In John Dickerson’s latest book, The Hardest Job in the World, he mentions The Eisenhower Matrix, and presents it as a tool that President Dwight Eisenhower used. There are no shortages of concerns that people would love to bring to any President’s attention, but in his estimation, the President should only be focused on Quadrant 1 and Quadrant 2 issues–the important things–and must deal with the issues in the time frame appropriate to each.


    I keep returning to the idea of this matrix. The simplicity disguises its effectiveness and it has become increasingly valuable to me since learning of it. Most of what I read is either non-fiction (predominantly in the social sciences) or news, and my media diet has never failed to provide concerns that I, as a citizen, am made aware of. In an election year–amid the volume swells & pounding of drums and when so many news events and issues are presented with such a feeling of importance–I feel this matrix really shines in identifying what is useful to focus on and avoid the traps of the season.


    Quadrant 1 is the Important and Urgent: I would place things like public confidence in a free and fair election or getting the Covid-19 pandemic under control in this block. Quadrant 2 would be the Important and Non-Urgent: I would place something like Comprehensive Immigration Reform or Nuclear Non-Proliferation efforts in this block.


    For Quadrants 3 and 4 “Less Important” feels like a more useful term. But for Quadrant 3, I would place restoring faith in Public Health Agencies and increasing public confidence in the value of expertise in specialized fields; in the distant corner of Quadrant 4, I might have some bit about the remodeling of the White House’s Rose Garden.

    In any event, I just wanted to share this. I find it useful to have the language available to immediately recognize something as a Quadrant 3 or Quadrant 2 issue in my own day-to-day and perhaps someone else who had similarly never come across the Eisenhower Matrix may as well.

    One of the biggest blind spots I had when living in North Florida, was a lack of interest in the estuaries and wetlands of N. Florida and S. Georgia. My favorite wild places as a young man in the area were the Okefenokee Swamp and the Long Leaf Pine forests of the Ocala and Osceola National Forests and I spent a fair amount of time tromping through them when I could. But nearby were hundreds of square miles along the Nassau River, the St. Marys, the Little and Big Satillas and all sorts of other tributaries and coastlands I largely neglected. Marshes, arguably more interesting–and unique in their abundance–were similarly neglected, outside of the areas on the edges I could walk to. The truly primitive areas are accessible only by boat.

    I’ve been thinking about that a lot this year, having visited my folks before the pandemic hit the US–and driving down from Atlanta, looking at many of these places from the higway–staring into the distance with older eyes. In retrospect, it seems that to know the Region, not just certain forests, but the unique character of the region, one needs a canoe. These ecosystems simply dominate the geography and are among the last primitive / wild places in the area and to my mind, dominate the natural character of the place.

    In any event – I just wanted to relay that point in case it lands with anyone. There is a lot of interesting outdoor ecology that you can’t just drive to in the area. As someone who strives to get well out into the wildernesses of the West Coast these days, it is interesting to consider that despite treks far afield to places like the Nantahala NF in NC, or the Everglades and Florida Bay far to the south, there were neglected areas in my own back yard, that could have been accessed more frequently with a modest investment in something as inexpensive as a used canoe or kayak.

  • The sourest dough

    August 15, 2020
    Uncategorized

    Since the pandemic began, like many, I’ve been making a few sourdough loaves of bread each week and periodically posting the results online. After dialing in a basic formula and method, my main focus has been on experimenting with various types of flours to explore the flavor profiles of different types of wheat while striving for a particular aesthetic (dramatic rise, open and consistent crumb). Laura Dakin and I were passing comments online recently though and she indicated that she prefers a more sour loaf and tends to modify her approach (by season, even) to accommodate her taste. When she explained what she was doing to make a more sour loaf, I gave it some thought but quickly realized that I did not understand what microorganisms in the mix were doing.

    If anyone isn’t familiar with it, sourdough is essentially an ecosystem. Folks who play with sourdough generally create and keep a small amount of starter on hand, which is simply a mix of flour and water serving as an environment for microorganisms — germs and fungus in this case (bacteria and yeast, respectively). Like any environment, it has a carrying capacity, and as the populations consume existing resources more are added to prevent the extinction of the organisms inside it. For reasons apparent to me now, I had mostly been considering the yeasts in the process of bread making and neglected the roles played by bacteria, despite the fact that the bacterial population may outnumber the yeast 100:1. Further, I did not ever really understand the biology of either organism and how they impacted flavor.

    In the US however, the baking industry produces $423 Billion in economic activity each year, producing about $30 Billion in annual revenue. This incentivizes funding for scientific research on the topic from both government and industry. (there are scientific journals, even!) In the civic sphere, there are also Public Libraries. And most libraries have online databases allowing citizens to access much of this research from the comfort of their own home. Thus, what I’ve gathered so far:

    The Bacteria:

    There are generally two types of bacteria found in a healthy sourdough ecology: AAB and LAB (and I’ll get to that). Fructilactobacillus sanfranciscensis is a famous bacterium endemic to the Bay Area and is likely present in my starter since that is where I live. Its day-to-day in a sourdough environment consists of eating carbs (glucose, from the flour, after a bit) and producing–among other things–carbon dioxide (CO2), ethanol and lots of lactic acid as waste products. Hence, it is an LAB: Lactic-acid bacteria. This Lactic acid generates a taste profile akin to yogurt (for reasons) and is responsible for that mildly tangy profile in many sourdough breads. Any AAB in a starter’s environment do their bacterial business by consuming glucose *and ethanol*, and excreting large amounts of acetic acid (and CO2 as well as other compounds). Since acetic acid is the primary component in vinegar, this is the origin of faint notes one might describe as tart or vinegar-like in various sourdough breads. Generally, LAB is dominant in most cultures. AAB generally favors a more aerobic environment (bread dough is anaerobic for the most part), competes better at cooler temperatures and has a competitive disadvantage in the the presence of lactic acid. (LABs, in this case, have a certain advantage in being able “to shit where they eat” despite conventional wisdom advising to the contrary.) Additionally, certain organic acids produced by LABs have antifungal and antimicrobial properties that may hinder the ability of AABs to compete in a shared environment. The majority of microbial research on the topic has been on LAB historically although more interest is being paid to the role of AAB lately and more will be learned as a result.

     Yeasts:

    The yeasts are also hungry for glucose. But being fungi, they have evolved to generate enzymes useful in decomposing their environment into more useful constituent parts. In this context, the yeasts break down the starches from the flour, converting them to sugars. And in doing so, we now have the beginnings of a synergistic relationship. By way of analogy, the yeast process the wheat (flour) to create sugar (glucose). They are exceedingly efficient and generate a surplus that the bacteria can use for their own purposes. The yeast (along with the bacteria) consume the newly liberated glucose molecules and the yeast excretes CO2 and ethanol in the proess. The latter, if you recall, is then also able to be consumed by AAB. A certain long-term symbiosis can be achieved if the bacteria and the yeast are able to gain a foothold in the starter as they will create an environment where food will be available thanks to the yeast, and interlopers will be kept at bay by the aforementioned antimicrobial properties arising from the organic acids produced by the LAB species.

    It’s kind of a beautiful thing. Particularly in the early days. A problem can arise from the ethanol production of the yeast after a spell though. Similar to how AAB does not do as well in the presence of the LAB’s primary waste product (lactic acid), LAB does not do so well in the presence of the yeast’s waste product (ethanol). So the balance can be precarious, but it is a fascinating ecology to consider. Three organisms at play: the yeast helping itself and providing one basic resource (glucose) to each type of bacterium, and a second resource (ethanol) to the ‘disadvantaged’ one’ in the process; the ‘disadvantaged’ bacterium removing a substance toxic to the dominant bacterium; the dominant bacterium generating a modicum of food (ethanol) in return and contributing mightily to the defense of the environment from outside organisms. All produce CO2, which is the mechanism behind the rising of the bread (without gas being generated, you’d just bake a brick). All have distinct niches and favorable conditions and the interplay is Sourdough ecology.

    None of this tells you how to actually make a loaf of bread of course, but it is useful in considering how to adjust one’s process to foster and ecology that produces the bread you want. Particularly if one can control distinct conditions in the bread making process. Information on the variable of temperature–perhaps the easiest variable to measure and control for any mix–are below.

    If the above is true–and why would you NOT believe something from someone named JMonkey you found on the internet?–at ranges outside of 65′ and 74’F, LAB populations can out-compete yeast.

    JMonkey jokes aside, the graph holds up, supported by a paper published by the Journal of Applied and Environmental Microbiology: Modeling of Growth of Lactobacillus sanfranciscensis and Candida milleri in Response to Process Parameters of Sourdough Fermentation. (authors: Michael G. Gänzle, Michaela Ehmann and Walter P. Hammes):

    In the weeks to come, I’ll likely try to put this to practical use.
